Video game about boy trapped in comic book unfortunately also trapped in horror genre

InvenGlobal tells about a video gaame titled Yurei, which is about the following:

Yūrei is a psychological horror game set within the haunted pages of a comic book, developed by Team Yūrei. The game was created over five months by ten second-year master's students from Cnam-Enjmin, the National School for Video Games and Digital Interactive Media in Angoulême, France.

Players must follow the comic's progression, reading the story to reach its end. The comic book, which is stuck to the protagonist Jun's hand, constantly speaks to the player, sometimes offering hints and at other times presenting challenges to solve. It acts like a narrator, yet it may also force you to make sacrifices.

The premise of being inside a comic itself may be clever, but making it part of an overused genre is not. It's regrettable the horror genre continues to be what's used as a theme for these kind of computer games, when here, if they'd wanted to, they could've turned it into a fanciful adventure with a brighter setting, yet they stick to potentially violent themes instead. That's the biggest problem with modern entertainment, and no telling how to convince anyone why it needs to change.

And I hesitate to think what they mean by "sacrifices".
